Work in progress: It's not yet possible to paste from the pane. The pane can be switched to and from and displays the strings recently added to the clipboard. ClipboardHistoryService listens for change to the system clipboard and keep the history in memory. This data is not persisted to the storage. The maximum size limits the amount of user data stored in memory but also gives a sense to the user that the history is not persisted and can be forgotten as soon as the app stops.
